Which type of insurgent approach invovles a few leaders?

The type of insurgent approach that involves a few leaders is often referred to as a "hierarchical" or "top-down" insurgency. In this structure, a small group of leaders makes key decisions and directs the actions of the broader insurgent group. This can lead to more coordinated efforts but may also create vulnerabilities if key leaders are captured or eliminated. Such a model contrasts with decentralized or grassroots approaches, where leadership is more dispersed among the ranks.
